Abstract

The present invention relates to a process for preparing chlorinated or partly chlorinated carbonyl compounds, which comprises reacting unchlorinated or partly chlorinated carbonyl compounds with a chlorinating agent in a jet loop reactor.

Claims

exact text as granted — not AI-modified
1. A process for preparing chlorinated or partly chlorinated carbonyl compounds, comprising reacting unchlorinated or partly chlorinated carbonyl compounds with a chlorinating agent in a jet loop reactor. 
     
     
       2. The process of  claim 1 , wherein a jet zone loop reactor is used. 
     
     
       3. The process of  claim 1 , wherein the chlorinating agent is one or more chlorinating agents selected from the group consisting of chlorine, sulfuryl chloride and thionyl chloride. 
     
     
       4. The process of  claim 2 , wherein the chlorinating agent is one or more chlorinating agents selected from the group consisting of chlorine, sulfuryl chloride and thionyl chloride. 
     
     
       5. The process of  claim 1 , wherein the unchlorinated or partly chlorinated carbonyl compounds are straight-chain, branched, or have a cyclic structure. 
     
     
       6. The process of  claim 1 , wherein the chlorinating agent is metered into the unchlorinated or partly chlorinated carbonyl compound in the reactor in a volume flow ratio of from 1:1 to 1:4000. 
     
     
       7. The process of  claim 1 , wherein the unchlorinated or partly chlorinated carbonyl compounds are used neat or in the presence of one or more solvents. 
     
     
       8. The process of  claim 1 , wherein the reaction in the jet loop reactor takes place at a temperature of from 20° C. to 160° C. 
     
     
       9. The process of  claim 1 , wherein the reaction is performed in the presence of a catalyst. 
     
     
       10. The process of  claim 1 , wherein the reaction takes place in a continuous or semicontinuous mode. 
     
     
       11. The process of  claim 1 , wherein the continuous addition of chlorine comprises recycling of unconverted chlorine into the circuit. 
     
     
       12. The process of  claim 1 , wherein the chlorination is effected both with and without partial recycling. 
     
     
       13. The process of  claim 1 , wherein the chlorinating agent is chlorine. 
     
     
       14. The process of  claim 1 , which is uncatalyzed. 
     
     
       15. The process of  claim 13 , which is uncatalyzed. 
     
     
       16. The process of  claim 1 , wherein the carbonyl compound is a 1,3-dicarbonyl compound. 
     
     
       17. The process of  claim 13  wherein the carbonyl compound is a 1,3-dicarbonyl compound. 
     
     
       18. The process of  claim 14  wherein the carbonyl compound is a 1,3-dicarbonyl compound. 
     
     
       19. The process of  claim 1 , wherein the carbonyl compound is a ketone, an aldehyde, an acetoacetate ester, an acetoacetamide, or a malonate ester. 
     
     
       20. The process of  claim 19 , wherein the chlorinating agent is chlorine, and the reaction is uncatalyzed.
